Multiple Enum Flags not rendering correctly in the Editor when custom PropertyDrawer values are changed

How to reproduce:

1. Open the “EnumFlagDrawerBug.zip” project
2. Open the “SampleScene“
3. Select The “Bug Demo“ GameObject
4. Change the flag of the “Test 02“ property in the Inspector window
5. Observe the “Bug Demo” script Component in the Inspector window

Expected results: The flag of the “Test 02“ drawer is shown correctly and is independent of the “Test 01“ drawer
Actual results: The flag of the “Test 02“ drawer is shown incorrectly and is dependent on the “Test 01“ drawer

Reproducible in: 2022.3.14f1, 2022.3.15f1, 2023.2.0a23, 2023.2.0b18, 2023.2.4f1, 2023.3.0a12
Not reproducible in: 2022.3.13f1, 2023.2.0a22, 2023.2.0b17, 2023.3.0a11
Could not test in: 2021.3.33f1 (No properties are shown because of “compile errors“)
Fixed in: 2023.2.0b1, 2023.3.0a2, 2023.3.0a18

Reproduced on: Windows 11 Pro
Not reproduced on: No other environment tested

Note: If some value is selected and the Mouse cursor is drawn outside the drawer box, the check mark will return to the “Nothing“ value
